Stylus-optimized PDF markup app for Windows and Surface devices rated the number-one engineering productivity app on the Windows Store, with a free tier for basic annotation.
3.6 /5 composite score

Rubric Scorecard
| Criterion | Score | Rationale |
|---|---|---|
| Maturity | 4/5 | Released 2013, rated number-one engineering productivity app on the Windows Store; regular updates with Pro Unlimited and AI credit add-ons added in recent releases. |
| AEC Specificity | 3/5 | Strong stylus and ink annotation with length/area measurement tools; lacks AEC-specific symbol libraries and Compare Documents-style drawing-set diff without the Projects upgrade. |
| Integration | 2/5 | Windows-first with web access; no native Procore or Revit plugins; annotation files stay within the PDF standard so they open in any viewer. |
| Value / Pricing | 5/5 | Free tier is genuinely useful for basic markup; Pro Lite is ~$50/year and Pro Unlimited ~$160/year; both are low-cost relative to Bluebeam. |
| Evidence | 4/5 | 4.3/5 on G2 from verified reviews; recognized by Microsoft as a flagship Surface productivity app; significant install base on the Windows Store. |
